Samsung Galaxy A21s Stuck on Boot Screen? Try this

It turns out that Samsung Galaxy A21s stuck on the boot screen are not uncommon, but they do happen. It can be triggered by adding a new app, upgrading to a higher operating system, or even installing an incremental Android OS. This issue basically restricts the boot screen so that you can’t see past the OEM logo.

Some of the devices may experience a slightly different problem: they will enter a boot loop in which the phone keeps rebooting itself. So, what should you do in that case? You can follow these few guidelines.

1: Perform a Forced Reboot [ Samsung Galaxy A21s Stuck on Boot Screen ]

A force reboot can break the chain if your Samsung Galaxy A21s is stuck on the boot screen or has entered a boot loop. It uses hardware keys and brute force to perform what amounts to a device reboot. You must determine the key combination based on your vehicle’s make and model. To force a reboot, you must press the Power + Volume Down or Power + Volume Up buttons.

Press and hold both buttons for at least 30 seconds until the Samsung Galaxy A21s shuts down after you have found the right combination. After a few seconds, you should be able to restart the phone by pressing the power button. If not, you can use the other strategies listed here to troubleshoot.

2: Boot into the Safe Mode

On your Samsung Galaxy A21s, Safe Mode is essentially a bootable safe mode in which all third-party processes and applications are stopped. You can determine whether a third-party app caused the device to become stuck in the boot loop because the phone is almost back to its default settings. You can attempt to resolve the issue in this manner by following the below instructions.

  • To begin, hold the “Power Off” button for a few seconds while simultaneously pressing the power button once to open the Power off menu. You will be prompted to enter “Safe Mode” at this point, so tap “Yes” or “OK” to confirm.
  • In the hope that this will resolve the issue, try removing some games and apps that you just downloaded from the system.
  • Simply pressing the Power button will allow you to exit Safe Mode.

If your Samsung Galaxy A21s behaves normally while in Safe Mode, the third-party applications are defective. But if everything works fine in this mode, you should definitely look for something else. To try to fix the problem, follow the next troubleshooting steps listed here.

3: Upgrade/Downgrade Software [ Samsung Galaxy A21s Stuck on Boot Screen ]

If your Samsung Galaxy A21s is stuck on the boot screen and you tried to upgrade to a newer Android firmware (which could be beta, incremental, or major upgrade) or if you considered downgrading, you need to take preventative measures.

Downloading the current firmware from your OEM’s website or other sources is required if you want to upgrade to a newer firmware. In a similar vein, in order to resolve the issue, if you attempted to downgrade, you will need to upgrade to the version that is currently available.

Updates from the SD Card can be applied in Recovery Mode. To use the “Apply Update from ADB” feature, connect the phone to the computer that has the ADB tools installed on it. You can use the Software Updates section in Settings >> About Phone to load and install new firmware if you can turn the phone on. Be careful before attempting this because it may result in the deletion of all user data.

4: Wipe Cache Partition

Try wiping the cache partition, which isn’t too invasive, before you take a big step and hard reset the phone (see the next method). Here’s how to go about it.

  • Turning off your Samsung Galaxy A21s will allow you to enter Recovery Mode. Hold Power + Volume Down or Power + Volume Up for 30 seconds at a time.
  • Release the keys and enter recovery mode as soon as you see an Android logo.
  • From the available options, you must select “Wipe Cache Partition” here. Again, there is no touchscreen in this model, so you will need to use the power button to select an option and the volume up or down button to navigate.
  • Finally, check to see if wiping the cache partition had any effect by selecting the “Reboot system now” option.

5: Pull off a Hard Reset [ Samsung Galaxy A21s Stuck on Boot Screen ]

There are a few things you should know before performing a hard reset. First, it will delete all of the data on your Samsung Galaxy A21s. You won’t be able to recover the deleted data unless you use a data recovery program. Second, it is frequently regarded as one of the most effective methods for resolving software-related issues; a technician is required for hardware-related issues. A hard reset can be performed in the following manner:

  • Turn your Samsung Galaxy A21s off.
  • Now, press and hold the Power + Volume Up or Power + Volume Down buttons simultaneously for thirty seconds.
  • When the phone boots into recovery mode, release both buttons.
  • Make sure you choose “Wipe data/factory reset.” Since you can’t use a touchscreen here, you have to use the power and volume buttons to navigate and select.
  • Select “Yes — delete all user data” as the next option, and the process will begin.
  • Finally, select the “Reboot system now” option to resolve the stuck boot screen issue.

6: Get a professional’s help

It turns out that performing advanced troubleshooting, such as unlocking the bootloader and flashing custom ROMs, can help resolve the issue. A qualified individual, such as a technician, can assist you at an authorized service center.
